Tomasz,
Re speed, the brite.js script pauses quite a while filling the stock
tree after each symbol fetch.

Is there a workaround to the call of 'AmiBroker.RefreshAll();'  for each
ticker?

Regards,

Bob

function Import( filename )
{
	try
	{
		AmiBroker.Import( 0, filename, DestDir + "brite.format" );
	}
	catch( e )
	{
		return false;
	}

	/* refresh ticker list and windows */
	AmiBroker.RefreshAll();
	return true;
}

If I implement changes into AB I have always the speed in mind.
Therefore newer versions should perform at least that fast as old ones.
In fact some enhancements have been made so 4.xx versions are
faster than 3.xx versions.
As far as 4.20 vs 4.29 are considered there is no difference.

THe best way to increase speed is to use variables whenever you can.
Instead of calling for example Foreign("$INDU","c") many times in your
code call it once and assign result to the variable.
